To ALE WHOM 1r MAY OONOEEN:

Be it known that we, GEORGE WALTE'ES and-THOMAS SHAEEER, ofPhoenixville, Chester county, Pennsylvania, have invented nn Improvementin Piles or Fagots for Wrougl1t-Iron Beamsor Girders;l and we do herebydeclare the following to be a full, clear, and exact description ofthesame.

Our invention consists of a pile Or fagot (for wrought-iron beams orgirders,) composed in part -of a solidv beam or beams, having a rib orribs, and in part of a number of bars .riveted together, and wedged to'the said rib or ribs, all as described hereafter; the parts of the pilethus composed being held firmly together while in the furnace, andforming, (after being subjected to the action of rolls,) a perfect beamorgirder of more than ordinary solidity. A

In Order to ena-ble others skilled in the art to make our invention, wewillnow proceed. to describel the mode' of carrying the same intoeffect, reference being had to tho accompanying drawing, which forms apart of this specification, and in which- 4 Figure 1 is a side view ofour improved pile or-fagot for wrought-iron 'beams or girdei's.

Figure 2, a transverse section of the same on the line 1 2, iig. 1, and

VFigures 3, 4,-and 5, sectional views of our improved piles or fagotsfor wrought-'iron beams of different shapes. I

)n reference to gs. 1 and 2, A represents the web ofthe pile or fagot,and Band B the two flanges. The web is, inthe present instance, composedof four plain bars a, 6, c, and d, riveted together, and each oftheilanges B and B is composed of a single solidbeam or bar, from one faceof'which, near one edgcof the bar, projects a rib, e. The bar a of theweb fits snugly between the flanges B and'B, but the bar d is as 'wideasthe-pile or fagot is deep, while theintermediate bars' b and c fitsnugly between the ribs e of 'the two flanges Band B', all as seen in g.2. Whether a singlebar, or more than two bars, are interposed betweenthe bars a and lel, the space between the latter should be wider thanthe ribs eof the anges arethiclc, so that when these ribs are confinedbetween the said bars, there may be a narrow space between theribs andthe bar z for the introdnction of wedges f, by driving which tight thewhole of the parts composing the pile aro held together. Four'wcdges areused, and are driven into their places at the two-ends of the pile, therivets c being situated nearfthe wedges, and preventing the latter fromforcing the bars a andd apart. The pile or fagOt-thus constructedisraised to a welding-heat in an ordinary furnace, and is then subjectedto the action of'the usualvrolls, and th'ereby .cnnverted into a solidand rigid beam or girder. l l

Fig. 3 represents a pilel or fagot for a beam of angular form, andis'constructed according to our improvement, in a manner which will bereadily understood withoutexplanation.

Fig. 4 represents a pile or fagot for a beam having a diii'erentsectional form, thewcb 'A being composed of a number-of plain bars,while the flanges l13 and B are solid, as described in reference to thebeam, tig. 2., In iig. 5 the pile or fagot is of the same sectional formas in iig. 4, but its anges B and 13v are composed of a number of barsriveted together and wedged to 1ribs e'on a web consisting of a solidbar.

We claim as our-invention, and desire to secure by Letters Patent-f 1 Apile er fagot (for wrought-iron bcamslcomposed in part of a solid -baror bars,` witha rib or ribs, e, and

in part of anumber of bars riveted together,.and`wedged to the said ribor ribs, all as set forth for the purpose specified.
